What Causes Steering Wheel Vibration When Speed Exceeds 100km/h?

[SophieFitz]

Reasons for steering wheel vibration when speed exceeds 100km/h: 1. Poor tire dynamic balance. During driving, if a tire is subjected to strong local impact, it may cause the balance weights to fall off or become damaged, affecting the tire's dynamic balance. At high speeds, the driver will feel obvious vibration in the body and steering wheel, with the vibration becoming more pronounced as speed increases. 2. Significant differences in tire pressure among the four tires. When there is a large difference in tire pressure between the four tires, especially between the left and right tires, the car will experience noticeable bumps and steering wheel vibration at high speeds. 3. Poor wheel alignment. When the wheel alignment angles deviate significantly, the car may exhibit body drift and vibration during high-speed driving; it can also cause uneven tire wear, accelerating tire wear and shortening tire lifespan. Therefore, if the steering wheel vibrates during high-speed driving, first check and adjust the tire pressure, then perform a four-wheel dynamic balance, and finally conduct a wheel alignment. This should resolve the steering wheel vibration issue during high-speed driving.
